1 '0 all whom it may cone-em: 3 Be it known that We, IIERBERT PEARCE and Jens ERNEST BILLIXGTON, subjects of the King of the United Kingdom of Great Britain and lreland, and both residing The Linotype and Machinery Works, Broadheath, in thecounty of Chester, England, have invented new and useful Improvements in the Production of Linotypes and Apparatus Thcrefor, of which the following is a specification.

in linot'ypc machines as heretofore coir structcd the characters on the matrices stand in an inverted position, or in other Words upside down, when in the casting position. The slotted moldin which the slug is cast against the horizontal line of matrices is mounted on a revolving wheel and theslugs are cast in an inverted position, that is to say with the hat side, which is next to the base of the characters, uppermost. The

niatriccs for all fonts, such as 6 pt, 8 pt,

etc, have their characters arranged at a common alining level at the top of the cap ital or pper case characters. It, therefore, matrices of such ditterent fonts are assembled in one line their characters as reproduced on the slug or linotype will be out of line at the foot or base.

In many classes of printing it is desirable to use in one line characters of different sizes or heights, belonging to diiierent V fonts. and to have them stand on a common base line, in order to accomplish this re suit depart from the past practice and arrange the characters on the matr ces oi two or more fonts of different sizes to aline at'the base of the capital or upper. case letters, so that when such matrices of different sizes are composed in one line and presented "to the mold they will produce, their characternon the slug or linotypc with a common basal alincmcnt. in order to permit the use of such matrices and at the same time permit variation ,in the thickness of the slugs according to'thc size of the ch; ctcrs in use, we hurt the slotted old in such manner that the side which ho. next the top of the matrix characters may be ad ed inward and outward toward and center oi he, a wheel in order the rrn dth of the slot. lVe a Specification of Letters Patent.

arrange the left-hand dresses the side of the slug next to the head or top of the characters so that it may be listed to receive the thickness of the slug required.

Among modern developments in the art f linotype production an attempt has been made to provide for basal alinement of characters or letters of diverse depths or sizes, such for example, as G, 8 and 10 pt. characters, on a linotype, and this Was proposed to be effected by making thecap of the mold a fixture, Whereas before it has been adjustable, and instead of the mold bottom being a fixture, as usual, the distance of its molding face from the molding face of the cap ing mechanism for operating the mold body 111 order to permit basal alinement of the charucti. Thus no time is lost in varying such a mold as the mold all is quickiy adjusted by the m prevent accidental movement, this invention provides a lock acting on, say, a cam bar which is employed in one construction for adjusting the lower mold Wall. v

The desccnders of the respective fonts vary in length or depth according to the body size of the characters of the said fonts or in other words the length of the descending portions below the m base varies with To accurately preserve the proach font. ortu n of every descender to its particular mat, would necessitate the ad ustment of the core" of the mold wheel, for every and although our improved he constructed so as to provide meats vet We do not consider city of adjustments desirable 1,, LJ" non a muiti.

necessary only when, after producing one of the four bodies included in one base group,

'it is desired to produce a body included in one of the other two base groups; these ad 'ajustments for variations of length of descenders are effected in substantially the ordinary way and differ from the existing ."practice only in so far as they are required at two specific changes of body size and not,

I 3 as heretofore, at every change of body size.

This invention further provides novel mechanism for adjusting the left hand-knife toward and from the right hand knife to ments, or, in the case of the mold cap being adjustable also, the invention provides such In order to adapt the device for dealing with two-line letters, the left hand knife may be longitudinally movable in known manner, or both knives may be longitudinally movable, and

a. sgecial mechanism will be described for ena ling a knife to be longitudinally movable or immovable at will. Further features of the knife adjustment comprise a laterally adjustable cam bar for adjusting the corresponding knife; a particular arrangement of springs for operating the knife against the action of the cam, bar; a

particular arrangement of locking device.

In the improved ing to the present invention and as shown best in Figsl, 2, 3 and 4, the face 1 of the mold body 2, or, in other words, that portion of the mold body' which constitutes the bottom of the mold slot 3, is' adjustable nearer to and farther from the center of the mold carrier or wheel 4, and the .mold body properwhich' is rigidly attached to the mold wheel, as ordinarily-is provided with suitable. means for guiding the movable portion, or mold bottom, as it is hereinafter mold constructed accord- '40 with which shoulder the upper er i ofbeing Lire-see called, during such adjustment.

The mold bottom 1., is provided with upstanding guides 36 whereon the mold cap 24 is slidable, the said mold cap being provided with end recesses engaging with those guides for constantly insuring proper registration between the mold cap and body; these guides 36 may also serve as stops for determining the fore-and-aft position of the before described body liners 25.

The before-mentioned keeper plate is secured to the mold body 2 by countersunk headed screws 37, and serves to retain .the

, cam bar lO'and pinion 18 in position when the mold is detached from the mold wheel 4.

The mold body 2 is provided with the usual alining ledges 38, 39, against one or other of which the rearmost bottom lugs 40 of the matrices l1, Fig. 8, are forced, as ordinarily during the casting operation. The ledges, through their engagement with the matrix ears, determine the vertical and longitudinal adjustment of the matrices across the mold slot, and thus determine the location of the type characters on the edge of the slug between its side faces. These alining ledges 39 are duplicated for the reason that each of the matrices 4-1 is provided with two formative cavities 42, 43. of respectively different faces or fonts, which may be alternatively brought into use, as is already well-known in the art. .according to the particular face required to be produced on the linotypes.

The mold wheel 4, shown in Figs, 1 and '2, is provided with'accommodation for two of the before described adjustable molds, at diametrically opposite parts thereof and it is also provided with foursockets i i whereof the two which, at the time of the actual casting of the linotypes, are in the-same horizontal plane, are adapted to receive pins 45, Figs..9, 11, 12. 16 and 18, fast on the vise frame 46, for insuring the proper registration of the assembled line of matrices 41 a'ndmold slot 3. By reference to Fig. 1, it will'be seen that one of the sockets 44. extends through the mold body 2, beneath the adjustable mold bottom 1, the said mold body. as shown best in Figs. 4 and 5, being provided with an aperture at? for receiving the said socket. It will be obvious that,

the descenders are grouped together in only if desired the just described arrangement of cooperating sockets and pins may be reversed, that is to say the sockets 44 may be provided on the vise frame 46 and the pins 45'n1ay be provided on the mold wheel-4.

Referring now to Fig. 8, the before mentioned system of grouping or alining the matrix characters of different sizes on a common base line is shown applied to a range of bodies varying in dimension from 3 point to 14 point as represented by theindications adjacent to those .respective bodies; the line maa is that which is arbitrarily selected as representative of-a given base line; in the case illustrated, it is the standard Roman m base. It will ,be seen that, so' far as regards the four bodies of from 3 to 6 point (both inclusive) there is no variation in the accommodation allowed. for the respective descendei's, one point being the uniform descender -allowance throughout these bodies, the gradual increase of these four bodies being upward from the m base so far as the actual type faces are concerned, and downward from the base line mw so far as regards the actual casting of the linotypes. Similarly with the four bodies ranging from 7 point to 10 point, there is a. uniformity of descender a1 lowanee (in this case two points) and a gradual increase or expansion relatively to the base line ww, and with the four bodies ranging from 8 point to 11. point there is a uniformity of descender allow ance (in this case three point'sl and a radual increase or expansion relatively to the base line acm. I W.

From the foregoing it will be seen that as three groups, it will be necessary to adjust the mold cap 2 1 only when, after producing linotypes included in one group, say the 3 to 6 point group, it is desired to produce linotypes included in say either the 7 to 10, or; the 11 to 14 point group. As each of'th various body dimensions throughout the range shown in Fig. 8 differs from its immediately preceding or succeeding neighbor, to the extent of only one point, it is to be noted that when any change which it is desired to make, involvesa change in either direction between 6 and 7 point,'or 10 and 11 point then the one point adjustment which must necessarily be given to the mold cap 24 fulfils all requirements, when. howe er. it is desired to change from a bodv includedin one group to another body differing to the extent of two or more points and contained in another of the groups, then it will be necessary to adjust both the mold cap 24 and the mold bottom 1; these just mentioned facts are to be borne in mind in view of the adjustments, hereinafter fully explained. which must also be given to the trimming knives.

linotypes ofthe same length but of'say point body size,

Fig. 7, suitable for the 1-1 mangoes the mold had been last employed for casting. linotypes of say 23 ems long and '14 point body. (body liners 25, and base. liners 30, to 14 point group havin been used for such purpose) and that it is esired to adjust the mold for casting 12 the operator first turns the eccentric 21 to release the cam bar. 10 and then, through the rack 17 and pinion 18 moves the'cam bar 10 toward the left of the machine so as to allow the mold bottom 1 to bedrawn by the springs 13 nearer to the center of the mold wheel 4. The operator then successively removes the 14 point body liners 25 and substitutes for them 12 point body liners 25, ward as far as it will go, so as to force the mold bottom 1 outward against the said substituted liners, and then turns the eccentric 21, so as to lock the cam bar 10 in position. The machine is then ready for casting the 12 point body linotypes, the base liners 30 not having been disturbed, because those then in position apply to the group (see Fig. 8 which embraces both the 14 and the 12 point body sizes. When the desired change is such as to call for another base, such forexample as a change from say body size, above exemplified,

body liners 25, as before explained, and sub- He next. releasesthe 11 to 14 point base liners 30 then in site, by loosening the screw 27, re moves those liners, and substitutes therefor the base liners which appertain to the 3 to 6 point group, after which, by means of the pinion 18, rack upward or outward-the inold bottom 1, body liners 25 and mold cap 24, until-stopped by the base liners 30 being jammed between the respective opposing surfaces of the mold cap 24 and mold wheel 4. this operation serving to secure the said base liners as also the body liners 25 in position. The operator then again tightens the screw 27 to completethe adjustment and thereby renders the mold ready for casting linotypes of the required 5 1 point body size.

With reference now, to Figs. 9, 10, 11 and 12, which show an improved arrangement of trimming mechanism, it will be seen that the vise frame 46 is of substantially ordinary construction, the only appreciable differ ences being such as are necessary owing to the left-hand knife 49 being adjustable; as Fig. 9 is a rear elevation, the left-hand knife 49 there appears to the right of the companion knife 48, and vice versa. The left? hand knife 49 is held to the vise frame 46 by two bolts or screws 50 which pass through slots 51 in the vise frame, as shown in dotted lines in Fig. 9, and are encircled by moves the cam bar 10 rightvheld in formed on a bar 59,'hereinafter referred to 85 the 14 point to a 5 point body size, the operator removes the 14 point bar 59, and which also admit parallelism of the two knives 17, and cam bar 10, he forcessprings 52, Fig. 11, which hold the said knife yieldingly against the rear face of the vise-frame."- This knife 49. isfree to slide horizontally nearer to and farther from the right hand knife48 and is direction by a key 53 Fig. 11, two coiled springs 54 always ten ing to move the said knife 49 away from its companion knife 48. Each of the, springs 54 has its two ends pro- 'jecting at right angles to one another, one

of such ends extending rearward through a slot or recess 55', see and engaging i'n a hole in the knife 49, the other end being securedin ahole in the vise frame 46, by-meansof a pinching screw 56.

At its left-hand side, the knife 49 1s provided with two inclined cams 57, Fig. 9, which, by the springs 54, are constantly contact with twoinclined cams 58,

as the cambar 59 capable of being moved longitudinally between the-back of the vise frame 46, and a guide 60 secured to the said vise frame. The guide 60 is provided with two studs 61 adjustabl bear against theback of the cam bar-59, and which, by adjustment, cause the knife 49 to occupy different lateral positions relativelyato given vertical positions of the cam being secured.

To. the lower end of the cam bar 59 there is connected, through a link .62, a. hand lever 63, and having its forwardly projecting end situated convenient to the hand ofthe op erator as shown best in Fig. 11. The hand lever 63 is provided with an index or pointer 64, Figs. 11 and 14, travel over a'plate 65 hearing indications such as shown in Fig. 14, which indicates the positions to which the lever 63, must be moved, in order to adjustthe knife 49 to correspond ment ofthe before-described mold bottom 1 in respect of the production of linotypes of different body size.

The cam bar 59 is provided with, or operatively connected to, a toothed rack 66, 115

Big. 11, with which engages a detent 67, under the influence of a spring 68, the saidspring being located, and the detent being slidable, in a barrel 69 fast to the vise frame 46. 70 cxtending'laterally through a slot in the barrel 69, for enabling the operator to withdraw the detent against the influence of the spring 68, out of engagement with the rack 66. the detent 67 are so shaped as to enable the left-hand knife 49 (through the medium of the hand lever 63) to be moved toward I i the knife 48, without necessitating the manual withdrawal of the detent out of en- 3 guided in that 70 particularly Fig. 11,

If desired the slot along which the arm 70 is movable, may be of L-shaped form to admit of the detent 67, when in its foremost position (and therefore disengaged from the rack 66), being locked in that position by'turning it about its axis vso as to cause thearm to engage with the tributary part of the said slot, and if desired also, the teeth of the rack 66 may be marked tov correspond with the markings on the indicator plate 65, and when so marked, may be used either conjointly with, or in substitution for, the said plate.

I-he right-hand knife 48, is acted upon by two coiled. springs 71 which tend to -move it rightward away from the companio'n knife +19, and it is adapted to be moved leftward by a movable cam bar 72 having one side Hat and bearing against the rightmost surface of, the-said knife, and the other-side provided with two inclined cams 73 bearing against studs 7i adjustable-in the knife block '75 which, as ordinarily, is secured to the vise'frame 46, by bolts and nuts 7 6.

Each of the springs 71 normally has its -two ends in the same vertical plane, as

shown best in Fig. 12, i? rear end engaging in a recess in the kni e48 and its front end secured in the knife block 75. The knife 48is yieldingly held against the rear face of the block 75, by means .of bolts 77 screwed into the said knife and passing through slots in the knife block, as shown in dotted lines in Fig. 9, and through spring washers 78 interposed between the heads of the said bolts and the proximate face of. the knife block 75. i I

The cam bar 72 isoperated by a hand lever 79 (Figs. 10 and 12) pivoted to the knife block75, and withits forked rear end engaging a pin 80 fast to the cam bar.

The hand lever 79 also carries an indezi or pointer Slavorkingover a plate 82 fast t'o'the knife block 75, this plate bearing indications to indicate the positions to which adjust the knife {l8 to correspond with the I respective adjustments of the before de- 'scribedmold cap 24, for the production of lines.

The spring-pressed detent 84:.i's providcd with a laterally-extending arm 87 capable of being manipulated by the-bperator similarly to the before described arm 70 and for a like purpose. 1

l'l'here both of the knives 48 and 49 are adjustable, two flapper plates 88 and 90 are pri'n'ided, for acting, under the influence of blade springs9l, on the respectively opposite sides of the linotypes. The flapper plate 88 is pivoted, as ordinarily, to the knife block and the flapper plate 90 is similarly pivoted to the vise frame 46, the

as has hitherto been the practice, the lefthand knife 49 is endowed with a capacity of vertical ad ustment as well as horizontal adjustment. For this purpose the said knife 49 is free to be moved vertically up and? down in a slide 92, Figs. 13 and 15, which is free to be adjusted in a horizontal direction on the vise frame 46. This adjustment is given to the slide 92, and through the saidas before described, for obtainingv slide, to the knife 49, by a vertically movable, 4

' The mechanism for vertically. moving the ing actuated in substantially the sa-ine man- I knife 49 may be similar tothat described for the same purpose in the specification of eithrBritish Letters Patent No. 12213 of 1897 or United States Letters Patent .Nuni- 1, her 910,489 dated January26, "-1999, in each} of which arrangements therev isfpresent a? lever of the third class acted upon by a cam fast to the cam shaft of the machine,andinf" I i to suitable fixed the latter of which arrangements this lever is compounded with another lever of the same class and provided with means whereby it may he moved out-oi operative a are ment with the cam to render the knife-mov- The lever 95 is operatively connected with the knife 49 through a bent link 96, and the lever 91, which is connectedto it by a pin and slot connection 97, is acted upon by the cam 93 through an anti-friction roller or. bowl 98 rotatable on an eccentric stud 99 capable of being rotatably adjusted in an arm, 100 which, by a pin 101, Fig. 18, is pivoted to the lever 91 at the end opposite to that at which it (the said lever) is connected to the lever 95. A weight 102 suspended from the lever 9% acts ,upon the latter antagonistically to the cam 93. ihe pivoted arm 100 is normally retained in its operative position, in line spring 103 and a stop constituted by its tail 101 which abuts against the said lever 9i as shown in Figs. 16 and 18. The spring 10 at its opposite ends, is attached to pins 105 projecting from the arm 100 and lever i spectively. hen the arm 100 is held in its normal or operative position by the spring 103 as shown in the drawings, the bowl 98 is v in the operative planezot' the cam 03. the said arm however,'is capable of being moved out of its operative position by means of a wire or equivalent 106 attached to a stud 107 projecting therefrom as shown best in Fig. 18, and which is drawn forward by the operator so as to move the bowl 08 out of the operathe plane of the cam 93, when there are no double line letters to be produced on the linotypes'. The wire 106 is guided through a stationary eye 108 and, at its forward end, is provided with a peg 109 capable of being inserted in either of two holes 110 according to the required position of the bowl 98.

As previously mentioned, to conform with the requirements of basal alinement, any in crease in the thickness of the ejector blade 111, Figs. 16, 10, 20 and 21, as necessitated by variations in the body size of the linotypes to be ejccted,,1nust be in a direction toward the center of the mold wheel 1, for

which reason the present improvements involve the cniployn'icnt oi an e ector mechanism substantiallysimilar to those now used in existing linotype machines, but with cer tain of the parts thereof reversed. Thus, in the new arrangcmcnhthe outer side of the ejector blade 111 (that isto say, the lowerparts of the machine frame? with the lever 91, by a most side in Fig. 19) whatever the thickness of such blade, is always practically in the same vertical plane and is in sliding contact with a fixed guide surface 112, and the inner side, where the variation takes place, Works in sliding contact with a spring guide 113. For this purpose any two ejector blades 111, whatever their respective thicknesses elsewhere, are of the same thickness at their rear ends at which they are secured to the ejector slide 113*, and the said ejector slide is 'pro vided with a checked surface which, together with the keeper plate 114 provides a.

recess or pocket of a size corresponding with that of the said end. The keeper'plate 114.

is secured to the slide 1.13 by screws 115, and the rear end of the ejector blade 111 is retained in the above named pocket-by means of pins 116 carried on blade spring 117, which pins enter holes in the said endv (as shown in dotted lines in, Fig. 19) or in any other of the usual ways. The ejector blade 111. shown in Fig. 19, isone of the thicker ones, but as stated its rear end at which it is secured to the slide 113 it is of the same thickness as the other blades, at' the forward end where it passes between the guides 112 and 113 and through the mold slot 3; this blade is considerably thicker than at its rear end but for some of the thinner linotypes an ejector blade may be uniform thickness throughout its length as will be well understood.

used which is of 0 5 in respects other than thosehereinhefore particularizcd, the ejector mechanism itself,

and the means for operating it, may be of substantially" the usual construction.

Ifdesired, the before-described improvements may be embodied in a machine which is capable of producing linotypes with twoline letters overhanging on both sides thereof, for which purpose both of the knives i8, 19 would 01, 95, would be capable of attachment to and detachment from each of such knives.

It is to he understood that the invention is not restricted to the specific construction of apparatus hcreinbe'fore described .with reference to the accoi'npanying drawings,

as the same incapable of many variations,

and modifications without the spirit of the invention.
